Elmhurst, IL; Grand Junction, CO, Rosemount, OH

The city of Elmhurst, IL (population 46K) is missing from CityStrides. James says it is missing a relation/way in OpenStreetMap. Could someone with knowledge of OSM make any changes necessary to get this city added to CS.

I also recently found that Grand Junction, CO (pop 62K) and Rosemount, OH (pop 2K, a suburb of Portsmouth) are also missing from CS. Any help in getting these added would be greatly appreciated.
